  <span><a name="intro"></a><h2 class="title">What is the PHP Exif Library?</h2><p>The PHP Exif Library (called PEL for short) is a library
    written in <a href="http://www.php.net/">PHP</a> which will allow you to
    manipulate <a href="http://www.exif.org/">Exif</a> data.  This is the
    data that digital cameras place in their images, such as the date
    and time, shutter speed, ISO value and so on.</p>

    <p>PEL makes it easy to parse Exif data stored in JPEG and TIFF
    images.  Once an image has been loaded, the data can be changed at
    will by manipulating the objects representing the data.  The
    objects can be saved again to produce a valid image.</p>

    <p>This documentation contains:</p>
    <ul><li><p>Full details on all classes and methods in PEL.  Begin
        with <a href="../PEL/PelJpeg.html">PelJpeg</a>.</p></li>

      <li><p>Instructions on <a href="../PEL/tutorial_using.pkg.html">Using PEL in applications</a>.</p></li>

      <li><p>A list of <a href="../PEL/tutorial_faq.pkg.html">Frequently Asked Questions (FAQ)</a>.</p></li></ul>

    <span class="warning"><p>Please note that PEL <em>requires</em> PHP
      version 5.  It will not run on PHP 4. See
      <a href="../PEL/tutorial_faq.pkg.html#why-php5">the FAQ</a> for more
      information.</p></span></span></div>
